A co-worker and I have been discussing a potential need for two different encodings of audio tracks. One would be an archival-level encoding for use on home audio systems. Another would be a lower-level encoding for use in car MP3 players, etc., where the goal is portability and where the noisy listening environment doesn't justify the high bitrates. Given a high bitrate encoding of a track, is there a good way to produce a lower bitrate encoding from it? Does MP3 data allow mathematical magic to produce a lower bitrate file without having to go back out to a WAV file and be re-encoded? For example, if data is encoded at CBR 192, is there some transformation on the data that can quickly give CBR 96? And if encodings are made from other encodings, are there artifacts that might appear? Something like a Moire' pattern in the data? Thanks in advance.
